Oh yeah! The mass penalty for those things is more or less nothing as long as they don't expand the armor envelope! I mean this ship of mine cares not at all about 1,000 of tons of anything additional as long as the armor volume increases a minimal amount!

My low power concept was to minimize power use from launchers and use missiles/drones. Currently, I have a small missle boat that uses a whopping 13kW of power. You can very easily minimize power consumption with drones and missiles, but still remain extremely lethal. Getting the mass and power for launching a say .. 100kW flare would likely be very simple.

If not for cap ships, it's still good for micro drones that need the cheapest reactors possible. Here's my reactor that goes in a 914 cr drone. Been trying to get it cheaper, but that's impossible until we can do our fuel and control rod weight in grams. Or maybe until we can do less than 100 watts for loader power. EDIT:Just managed to make this thing for half the cost, reduced the autoloader and reaction wheel energy cost of my drone to 100W to fit it. My drone now only costs 635 cr. No idea how in all tarnation I managed to use depleted uranium as a fissile material.

Umm... Depleted uranium means it no longer has any meaningful amount of fissile material in it... So I have no idea what so ever how you can make any reactor that uses just that. Also what does purity even mean for that fuel considering it's what leftover after refining uranium? I am so confused.

Depleted uranium still has 0.3% worth of U-235 in it.

Depleted uranium still has 0.3% worth of U-235 in it. That's true but I mean for nuclear reactors you want a lot of U-235. I don't think that amount of U-235 is even capable of sustaining a chain reaction (I just checked, it is not fissile.)... And again what even is refinement level for depleted uranium as the higher it is the less fissile material it has right...? I am just really confused for how you can use the leftovers from nuclear refining to make nuclear power when it is considered to not even remotely be a radiation hazard... Also I now have some shiny new flares! This is the cheapest one This is the smallest one (dimension wise):

Here's a new contender for cheapest reactor that is also lighter than all others i have seen so far: (not pictured: 1cm 1RPM hydrogen/lithium external coolant pump) You can get it to output more energy by increasing neutron flux and cooling, though i prefer the lower radiation output instead. Oddly, switching to a boron/boron nitride/boron carbide material for control rods reduces the reactor's mass by 0.02kg, though i don't know why exactly this happens.

It actually looks like a fucking Duracell battery now.

If only I could set that exit temperature just a bit lower... On a side note, we need the ability to set fuel masses for RTGs to the gram range. Currently super small reactors are taking over for ultra low cost drones. Attachment Deleted

Tritium wouldn't be efficient mass-wise because of the sheer amount of radiators you would need.
at a 16 K exit temperature(which you'd need to keep the current efficiency), you'd need 138594 m² of radiator area. Even at 21 K that's still 46704 m². At this point using a heat pump could actually significantly reduce radiator area, but i haven't done the math on what efficiency figures you'd get out of that and whether it's viable.

I'm more interested in subcritical reactors instead.

Here is my nano drone: childrenofadeadearth.boards.net/post/2193/threadIt's a tiny bit heavier but cheaper. My post also has every single component that went into it.
